A domestic dishwasher is not a general degreasing cabinet. Oils, fuels, solvents, metal fragments and unknown coatings can create contamination or safety concerns.
Understanding this situation
The appliance and detergent are intended for permitted household items under their instructions. Removing visible grease does not establish that the machine is suitable for food-contact dishes afterwards.
A useful next step
Use an appropriate specialist cleaning route for workshop components. If unsuitable substances have already entered the appliance, disclose them before service and do not add more chemicals to neutralise them. Avoid running hot cycles to evaporate residues.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
